Patent GB-1251855-A (GB)
IPC: G06K7/10
Filed: 1969-06-20
Abstract: 1,251,855. Sensing records. INTERNATIONAL BUSINESS MACHINES CORP. 20 June, 1969 [8 July, 1968], No. 31203/69. Heading G4M.  Each mark area 25 is scanned by a light spot in a plurality of parallel lines to produce a sense signal each time the spot crosses a mark, and the sense signals are examined to determine whether the scanned mark is valid. Scanning operation.-An external source, e.g. a computer, supplies terminals 56, 58 with signals representing the co-ordinates of a starting point A and sets latch 66 so that controls 54, 48 position the beam of CRT 46 at point A, H and V beam position signals being fed back to control 54. Latch 66 is then reset and logic 78 starts a fast scan downwards. When a timing mark 22 is detected by photomultiplier 43, the V beam position signal is stored at 80, and a predetermined distance later in the vertical sweep (position B) the V beam position signal is stored at 82, the reset signal to counter 96 is removed and a small raster scan is started. The first up-sweep scan in which timing mark 22 is not crossed is detected at 84 and an H beam position signal corresponding to the centre of mark 22 is stored at 86. Logic 90 causes a fast left sweep to be superimposed on part of the next up sweep CD (VSR1-VSR20) to cause a jump to the first mark position. Scanning of the first mark position continues for 20 up sweeps (counter 102) when a jump EF is made (VSR1-VSR30), the gap between mark positions being greater than that between timing mark 22 and the first mark position. Scanning continues in this manner until the end of the last mark position G when counters 100, 102 set latch 66 to cause the CRT beam to be retraced to position H (actually the same as B) under control of the signals stored at 82, 86. Detection of the next timing mark and scanning of the next row take place in a similar manner. Mark signal processing.-Timing circuit 76 rejects narrow pulses from thin marks. Logic 88 provides a gating period for mark sense signals during part of each up sweep, VSR16- VSR30 for timing marks 22 and VSR8-VSR30 data mark positions, the timing marks being displaced vertically from the rows of mark positions. Logic 92 receives the mark positionidentifying signals DA1-DA12 and provides a signal on a corresponding output provided a minimum number of mark sense signals are detected during the scanning of a mark position. Logic 94 provides an output if a small number of mark sense signals are obtained during scanning of a mark position e.g. for a partially erased mark and gives an indication (not necessarily unambiguous) of which position is involved.

Abstract: 1,264,588. Measuring current in high voltage lines. TRANSFORMATEURS DE MESURE WALTER. March 10, 1970 [March 10, 1969], No. 11427/70. Headings G1A and G1U. [Also in Division G2] An optical system, especially for measuring current in high voltage lines, comprises a light bulb S whose light output passes through lens O1 to a semi-transparent mirror M which reflects the light along axis A. The light then passes through a first transparent element F1, e.g. a flint having a high Verdet constant, a second lens 02 and a second transparent element F2 similar to F1. The rear face of element F2 is metallized so the beam is reflected back along the axis to pass through semi-transparent mirror M, lens 05 to photodetector PD. In use element F2 is positioned in the magnetic field of the current being measured and element F1 is used to compensate for the rotation of the plane of polarization thus providing a measure of the current. The arrangement is such that the incoming light is focused by lens 02 on to the front surface 03 of element F2 and is reflected at the back face 04 through a coincident point P1, P2 on front face 03 into a focused point P3 on lens 05. This is stated to prevent the image S4 moving due to disturbances such as bending or vibration. In a practical embodiment the elements F1, F2 and lens 02 are housed in a rigid structure which may contain an inert gas, Fig. 2 (not shown).

Abstract: 1,265,304. Yarn drawing apparatus. COURTAULDS Ltd. 10 July, 1969 [11 July, 1968], No. 33095/68. Heading B5B. [Also in Division D1] A yarn drawing machine comprises a feed roller and a draw roller, the draw roller 10 having a flange 13 with a peripheral surface 14 which frictionally contacts the yarn 2 passing on to the draw roller so as to false twist the yarn, and means for heating the yarn before it passes to the flange of the draw roller, the peripheral surface of the flange being the surface of rotation generated by a straight line connecting the points at which the yarn makes and breaks contact with the surface. The flange may be moulded from hard rubber. From the feed roller, the yarn is passed round a snubbing pin which may be heated and then through a heater, and is then passed over the flange 13 and wrapped round the draw roller 10 and a separator roller 11. Because the flange peripheral surface 14 has a greater linear speed than the draw roller surface 15, the yarn 2 is false-twisted and the twist runs back along the yarn through the heater as far as the snubbing pin, and the yarn is given potential crimp which may be released on subsequent relaxation.

Abstract: 1296311 Load responsive vehicle brakes SVENSKA AB BROMSREGULATOR 7 April 1971 9004/71 Heading F2F [Also in Division G1] The load on a vehicle is sensed by a pneumatic load cell 1, 2 mounted between the spring 28 and vehicle frame 23, and the pneumatic load signal may be applied to a brake regulation device (not described). The load is applied to a piston 7 and transmitted through a plastically deformable solid 8 such as polyethylene to the small diameter part 10 of a piston 11, the force thus applied to part 10 being automatically balanced by pneumatic pressure applied to the large diameter part 9 of the piston and the pneumatic load signal being taken from part 18 in communication with the chamber over piston part 9. In the equilibrium position of the device,  the piston is positioned such that valve member 12 seats against both valve seat 16 and the top of piston 11, and the chamber above piston part 9 is thus isolated from pressure source 17 and exit 13. If the load on piston 7 increases, piston 11 is moved upwardly and pushes valve member 12 from valve seat 16 to allow air from source 17 to enter the chamber above piston part 9 until the equilibrium is again established. If the load on piston 7 decreases, piston 11 moves downwardly and allows air to escape from the chamber above part 9 through exit 13 until the equilibrium position is again established.
